Do you think the other 3 you listed would last 10 hours? The Pro gets less battery life than the Air. Even if just an hour or two it probably wouldn't meet your criteria. Is 10 hours even possible on Windows?

We average 6 hours of mixed use with automatic brightness disabled and display brightness set to 50% with WiFi and Bluetooth turned on. If you use a more power frugal plan setting (we used Balanced) or enable silent mode and drop the brightness a bit, you could get 7 hours.

Looks like maybe the IdeaPad Yoga 2 could get you 10 hours..CNET said 7 hours of continuous video playback..but that's a Win8 half-tablet convertible thing..if you want one of those, I don't know if it and an Air are comparable on anything other than battery life?
